目的评估多层螺旋CT(MSCT)对伴巨大倒置T波的心尖肥厚型心肌病(AHCM)的诊断价值.方法 16例伴巨大倒置T波的AHCM患者(AHCM组)行MSCT、超声心动图、心电图、冠状动脉及左心室造影检查,其MSCT结果与30例无心肌增厚患者(对照组)进行比较.结果 MSCT均正确诊断AHCM,超声心动图10例漏诊.MSCT图像上AHCM组舒张末期左心室心尖部厚度(LVA)为(21.3±3.6) mm,舒张末期LVA/左心室基底段后壁厚度(LVPW)为2.2±0.4,均显著高于对照组的(8.5 ± 1.6) mm和0.9±0.2,差异有统计学意义(P＜0.01).结论 MSCT能准确诊断伴巨大倒置T波的AHCM,实现了心脏解剖和冠状动脉的综合评价.

Objective To investigate the clinical value of multiple-slice spiral CT (MSCT) in identifying apical hypertrophic cardiomyopathy (AHCM) with giant negative T wave.Methods Sixteen patients with AHCM and giant negative T wave (AHCM group) underwent MSCT,electrocardiogram,echocardiography,coronary angiography and left ventriculography.Thirty patients without myocardial hypertrophy were enrolled as control group.Measurement results of two groups were compared.Results MSCT confirmed all patients with AHCM,but echocardiography missed 10 patients.In the end of diastole phase,left ventricular apical thickness (LVA) was (21.3 ± 3.6) mm and LVA/left ventricular posterior wall thickness (LVPW) was 2.2 ± 0.4 in AHCM group,which was (8.5 ± 1.6) mm and 0.9 ± 0.2 in control group.The level of LVA and LVA/LVPW in AHCM group were significantly higher than those in control group (P ＜0.01).Conclusion MSCT is a accurately diagnostic modality for AHCM with giant negative T wave,and the cardiac anatomy,function and coronary artery are also assessed simultaneously.
